CORN PICK ER.

Application filed January 28, 1922.

T 0 all whom it maqe concern:

Be it known that I, JAY A. BUGKTNGHAM, a citizen of the United States, residing at Alta, in the county of Vista and State of Iowa, have invented certain new and useful Improvements in Corn Pickers, of which the following is a specification.

This invention relates to corn harvesters of the type in which gathering and snapping rolls are supported above and to the left of one ground wheel by extensions of the main frame and brackets "fitted to and rising from the axle of said wheel, husking rolls are supported above the main frame at the right side of the se me and at the right of the other, ground wheel, and a conveyer is disposed bet *cen the sets of rolls to effect travel of the corn from the gathering and snapping rolls to the bushing rolls, the object of the invention being to dispose the driving mechanism so that it will operate efliciently butwill not take up trash and become clogged when operating in damp weather. The invention is illustrated in the accompanying drawing and will be hereinafter fully set forth.

In the drawing Figure 1 is a plan view of a portion of the main frame of a corn picker and husker having my improvements embodied therein;

Fig. 2 is a detail side elevation of a por tion of a ground wheel;

Figs. 3 and f are detail views showing parts of the escapement mechanism whereby the rotation of the driving wheel is imparted to the main shaft or axle.

The main frame, as illustrated in the accompanying drawing, comprises the cross bars 1 and 2 and the stringers or sills 3 connecting them as said parts are now arranged and constructed. The axle or main shaft 4 is mounted in bearings 5 secured to the under sides of the stringers or sills 3 at a pointin advance of the center of the same and so disposed that ample clearan e will be provided between the axle and the stringers. The ground or driving wheels 6 are 'mounted loosely upon the axle or main shaft and the inner ends; of their hubs provided with flanges or casings 7 constructed with internal teeth 8 to be engaged by dogs 9 carried by disks 10 which are fixed to the axle adjacent the outer ends of the bearings 5. The dogs 9 are seated in recesses within the disks and are normally pressed outwardly by springs 11 disposed between the dogs and Serial No. 531,980.

co-operating abutments 12. When the machine is being drawn forwardly, the teeth 8 of the casings 7, which are fixed to the ground wheels, will engage the ends of the dogs 9 so that the said dogs will be carried around with the flanges or casings 7 and consequently the axle 2 will be rotated. Should the machine be moved backwardly, however, the teeth will merely slip over the ends of the dogs without imparting motion through them to the disks and the axle. The right-hand driving or ground wheel 6 is disposed at the outer side of the main frame but the lefthand driving wheel is disposed between the left hand stringer and the brackets or extensions supporting the frame of the gathering and snapping rolls, and an additional longer bearing 13 is provided to support the adjacent end of the axle, this hearing 13 being connected with the adjacent parts of the main frame and the sup ports for the gathering and snapping rolls in any convenient manner. The driving or ground wheels are provided midway their ends in their peripheries with circumferen tial grooves 14 and upon the tread surfaces of the driving wheels at each side of the said groove are traction lugs 15. As shown most clearly in Fig. 2, these traction lugs are in clined rearwardly with respect to the direction of movement of the wheels so that, while they will readily enter the ground and provide the necessary fulcrum or propelling force, they will easily and efficieutly clear the ground as the machine progresses so that the lugs will not be apt to pick up loose pieces of corn stalks or other trash as the driving wheels rotate.

In rear of the axle or main shaft 4-, a cross bar 16 is secured to and extends between the tringers and the stub tongue 17 is secured t its rear end upon the said cross bar, the tongue passing through and being secured in a clip or bracket 18 on the front cross beam 1, as clearly shown. The tongue is supported at its rear end in such manner that it will pass above the axle or main shaft 4 and will provide clearance above the axle for a brace 19 which extends diagonally from the front end of the left-hand stringer 3 to the cross bar 16, as clearly shown. This brace passes between the tongue and the axle and while it aids in imparting the necessary rigidity to the main frame it is so arranged that space is provided between the brace and the tongue at one side and the left-hand stringer 3 at the opposite side for a driving sprocket 20 which is keyed to the axles and is operatively connected by a sprocket chain 21 with a sprocket pinion 22 on the shaft 23 from which motion is imparted to the picking and husking mechanism, not shown.

The sprocket 22 is loose upon the shaft 23 but may be locked to the shaft by a clutch 2% which clutch is set in operative or inoperative position through m'anlpulation ofa hand lever of the usual construction and which is not illustrated herein as it forms no part of my present invention and the show- 7 ing of the same would tend to confuse the drawing. The front end of the stub tongue is coupled to the usual front truck.

the arrangement herein shown and described, the sprocket and the chain trained around the same are disposed an appreciable distance from the ground wheel and arranged between the longitudinal stringers so that ample clearance is provided for any trash which n'iight tend to be carried around with the chain and clogging of the operation is avoided inasmuch as such particles of trash s would otherwise cling to the chain may readily drop therefrom and will be shaken loose as the chain travels with the sprockets. Moreover, the tongue is supported in such a manner that it will be held more rigidly in its position and is more apt nal stringers secured to andfextending be tween the cross beams, of a cross bar disposed between and secured to the stringers in advance of the rear ends thereof, a diagonal brace extending between one of the stringers and the said cross bar, a tongue secured upon the cross bar and the front cross beam anddisposed above thesaid brace, an

axle mounted on the under sides of the stringers, a sprocket fixed upon the axle between the tongue and one of the stringers and also between the brace and the said stringer, ground wheels loosely mounted upon the axle at the outer: sides of the stringers, means for operatively connecting the ground wheels with the axle, and means for transmitting power from the said sprocket to parts to be driven.

In testimony whereof I signature.
